본 고안은 공작기계용 볼스크류(Ball Screw)에 관한 것으로, 특히 직교 좌표의 정밀도 유지에 직접 관련되는 볼스크류의 자중에 의한 처짐을 방지할 수 있도록 한 볼스크류의 처짐 방지장치이다.The present invention relates to a ball screw (machine ball screw) for machine tools, in particular, a ball screw sag prevention device to prevent sag caused by the weight of the ball screw directly related to maintaining the accuracy of Cartesian coordinates.
종래에는 제3도에 도시한 바와 같이 스크류 너트홀더(30)에 설치된 도그(32)가 리미트 스위치(33)를 치면, 공압 실린더로 작동되는 지지대(34)가 급속히 하강하여 홀더(30)는 지지대(34)를 피헤 볼스크류(31)상에서 이송하며, 지지대(34)가 설치된 부분을 홀더(30)가 통과하여 도그(32)가 리미트스위치(33)로 부터 이탈하면, 지지대(34)공압으로 상승하여 볼스크류(31)를 지지하게 된다.Conventionally, as shown in FIG. 3, when the dog 32 installed in the screw nut holder 30 hits the limit switch 33, the support 34 acting as a pneumatic cylinder descends rapidly, and the holder 30 is supported. (34) is transported on the phise ball screw 31, the holder 30 passes through the portion where the support 34 is installed, the dog 32 is separated from the limit switch 33, the support 34 by pneumatic As it rises, it supports the ball screw 31.
이러한 구조는 도그의 작동상태를 체크하기 위한 전기식 신호장치와 지지대를 작동하기 위한 구동장치가 필요하게 되므로, 부품의 증가와 제작비의 증가로 제품의 원가상승 요인이 되었으며, 고장율이 높기 때문에 사용함에 있어서 많은 결점을 내재하고 있는 것이다.Such a structure requires an electric signal device for checking the operation state of the dog and a drive device for operating the support, which increases the cost of the product due to the increase in the number of parts and the increase in the manufacturing cost, and the high failure rate. Many defects are inherent.
본 고안은 상기한 종래의 문제점을 해소하기 위한 것으로, 첨부한 도면에 의거하여 상세하게 설명하면 다음과 같다.The present invention is to solve the above-mentioned conventional problems, described in detail based on the accompanying drawings as follows.
제1a도에 보인 바와 같이 기판(15)상의 양측에 설치된 프레임(14)(14')상의 가이드레일(12)(12')에 가이드 홈이 마련된 테이블(1)의 슬라이드 베어링(13)(13')을 결합하고, 상기 테이블(1)의 중앙에 볼스크류(10) 및 볼스크류 너트 홀더(11)가 부착된 통상의 것에 있어서, 테이블(1)의 양쪽에 도그(2)(2')가 설치되고, 상기 도그(2)(2')에 대응하여 작용하도록 로울러(3)(3')가 구비되며, 상기 로울러(3)(3')를 상부에 설치한 종절안내봉(5)(5')은 기판(15)에 수직으로 고정설치된 두 개의 가이드(4)(4')주벽의 승강 안내홈(16)(16')내에 끼워진 운동핀(7)(7')에 의해 상기 볼스크류(10)을 지지하는 지지대(8)를 중앙에 고정 설치시킨 구동아암(6)과 연결고정되며, 또한, 상기 운동핀(7)(7')에 행정거리 내에서 승강동작을 행하게 되는 것이다.As shown in FIG. 1A, the slide bearings 13 and 13 of the table 1 are provided with guide grooves in the guide rails 12 and 12 ′ on the frames 14 and 14 ′ provided on both sides of the substrate 15. '), The ball screw 10 and the ball screw nut holder 11 is attached to the center of the table (1), the dog (2) (2') on both sides of the table (1) Is installed, the roller (3) (3 ') is provided to act in response to the dog (2) (2'), the longitudinal guide rod (5) having the roller (3) (3 ') installed on the top 5 'is defined by the motion pins 7 and 7' fitted in the elevating guide grooves 16 and 16 'of the circumferential wall of the two guides 4 and 4' fixedly mounted perpendicular to the substrate 15. It is fixed to the driving arm (6) fixed to the center of the support (8) for supporting the ball screw 10, and also to the lifting pins (7) (7 ') to perform the lifting operation within the stroke distance will be.
그리고, 상기 지지대(8)는 볼스크류(10)에 대응하여 그 직하방에 설치된 어퍼스프링(9)위에 얹힌 상태로 볼스크류(10)를 지지하는 주는 것이다. 이러한 구성의 본 고안은 제1a, b도 및 제2도에 도시한 바와 같이, 테이블(1)이 이송을 할 때 테이블(1)에 설치된 도그(2)(2')가 구동아암(6)의 양측에 연결설치된 안내봉(5)(5')의 상단 로울러(3)(3')에 접촉하게 되면, 안내봉(5)(5')의 로울러(3)(3')가 도그(2)(2')의 주면을 따라 미끄럼 운동을 함에 따라 구동아암(6)을 압하하게 됨에 따라 구동아암(6)은 스프링(9)을 제압하면서 지지대(8)를 하강시키게 되므로, 볼스크류 홀더(11)는 지지대(8)에 충돌됨이 없이 그 상부를 통과하게 되는 것이다.And, the support (8) is to support the ball screw 10 in a state mounted on the upper spring (9) installed directly below the ball screw (10). In the present invention of this configuration, as shown in Figs. 1A, 2B and 2, the dog 2, 2 'installed on the table 1 is driven by the driving arm 6 when the table 1 is transported. When contacting the upper roller (3) (3 ') of the guide rods (5) (5') connected to both sides of the roller, the roller (3) (3 ') of the guide rod (5) 2) As the slide arm moves down along the main surface of 2 ', the driving arm 6 is pushed down so that the driving arm 6 lowers the support 8 while pressing down the spring 9, so that the ball screw holder 11 passes through the upper portion of the support 8 without colliding with the support 8.
이때 도그(2)(2')가 안내봉(5)(5')의 상부를 완전히 지나게 되면, 지지대(8)하측의 스프링(9)의 복원력에 의해 지지대(8)는 상승하여 하강전과 같이 볼스크류(10)를 지지하게 되므로서 볼스크류(10)의 처짐을 방지하게된다.At this time, when the dog 2, 2 'passes completely through the upper portion of the guide rods 5, 5', the support 8 is raised by the restoring force of the spring 9 below the support 8, so as to be lowered. Since the ball screw 10 is supported, sagging of the ball screw 10 is prevented.
이와 같은 본 고안은 기계적인 방법에 의해 볼스크류를 지지하므로서, 보다 확실한 지지를 할 수 있고, 복잡한 전기 신호 장치와 구동장치가 필요치 않음으로, 제작이 용이하고 경제적이며, 보수 및 점검이 용이한 효과를 얻을 수 있는 고안인 것이다.The present invention supports the ball screw by a mechanical method, so that it can be more reliably supported and does not require a complicated electric signal device and a driving device, and is easy to manufacture, economical, and easy to repair and inspect. It is designed to get.
